Christmas candlestick

The Christmas candlestick (Cassia alata), more commonly known as candle bush or ringworm bush, is a shrub or small tree in the family Fabaceae, native to the New World tropics, primarily Central America, Mexico, and northern South America. The species is widely naturalized throughout the tropics and subtropics globally, having spread through cultivation and accidental introduction. It produces distinctive upright, spike-like racemes of bright yellow flowers that resemble a lit candelabrum, giving rise to its common names. These inflorescences are borne at the tips of branches and can reach up to thirty centimeters in length. The large pinnate leaves are characteristic of the genus Cassia. Cassia alata has been used extensively in traditional medicine across its native and introduced range, particularly for treating fungal skin conditions such as ringworm, a use supported by documented antifungal activity of compounds in the leaves. The species grows rapidly in disturbed habitats, roadsides, and forest margins, and is considered weedy in many regions. It is a host plant for the larvae of several sulfur butterfly species. While not a significant conservation concern, its invasive tendencies in non-native regions warrant management attention.

Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
